24-Bit FET Bus Switch With Level Shifting

The SN74CBTD16211 provides 24 bits of high-speed TTL-compatible bus switching. The low on-state resistance of the Switch allows connections to be made with minimal propagation delay. A Diode to VCC is integrated in the circuit to allow for level shifting from 5-V signals at the device inputs to 3.3-V signals at the device outputs.The device is organized as a dual 12-bit bus Switch with separate output-enable (OE) inputs. It CAN be used as two 12-bit Bus Switches or as one 24-bit bus Switch When (OE) is low, the associated 12-bit bus Switch is on, and port A is connected to port B. When (OE) is high, the Switch is open, and the high-impedance state exists between the ports. By Texas Instruments
